THE ZooLOGIST—FEBRUARY, 1875. 4347 
all described in the October number of the ‘ Entomologist’s Monthly Maga- 
zine, p. 109; together with three curious bud-galls, unknown, from 
Rayleigh, Essex. 
Mr. Champion exhibited an interesting collection of Hemiptera, brought 
from the Mediterranean by Mr. J. J. Walker. Amongst them were Trigo- 
nosoma Desfontainei, from Cagliari; Phyllomorpha laciniata, from Gibraltar ; 
and Prionolytus Helferi, from Tangier. 
Prof. Westwood forwarded a letter he had received from Mr. J. F. M. 
Harris Stone, accompanying a sample of tea imported from Shanghae, 
infested by a small beetle which proved to be the Ptinus hololeucus, an 
insect belonging to a genus, the species of which feed indifferently on dried 
vegetable as well as animal matter. 
Prof. Westwood also communicated a letter from Prof. Forel, of Lausanne, 
stating that the Phylloxera vastatrix had made its appearance among some 
vines at Pregny, in the canton of Geneva, which had been introduced from 
England into the graperies of Baron Rothschild, and that the Phylloxera 
had been discovered in two of his greenhouses, among vines planted in 
1869, sufficiently distant from each other to render it improbable that the 
insect had been communicated one from the other; and he therefore 
concluded that the disease had been introduced in 1869 from the graperies 
in England. The vines so attacked had, however, not succumbed to the 
disease, but were simply rather weaker than those which had not been 
attacked. He was, therefore, anxious to ascertain whether the vines in 
the English graperies were less influenced than those out of doors; but 
none of the Members present were aware of the occurrence of the insect 
in England out of doors, but that it had hitherto appeared in greenhouses 
only. 
Mr. C. O. Waterhouse communicated the following ‘ Synonymical Notes 
on Longicorn Coleoptera : "— 
“ Fam. PRIONIDA. 
Acanthophorus Palinii, Hope. This species was placed by Mr. Adam 
White, with doubt, as Acanthophorus Yolofus of Dalman, and in Gemminger 
and Harold’s ‘ Catalogue of Coleoptera’ they are placed together without 
even a doubt. There being, however, in the British Museum a species of 
Tithoés (to which genus A. Palinii must now be referred), which I believed 
to be the true A. Palinii, I referred to Prof. Westwood, who kindly sent to 
me a sketch of Hope’s type in the Oxford Museum, confirming my deter- 
mination, and making it certain that A. Yolofus and A. Palinii are quite 
distinct species. Tithoés Palinii resembles T. confinis, but is shorter; the 
eyes are much approximated above; the thorax is broadest in front, with 
the anterior spine strong (much longer than the lateral spine), and very 
much recurved; the elytra are marked much in the same way, but the
